The answer is 2 rupees
1kWh = 1 BOT unit
1kWh = 1000*60*60 J = 3.6 * 10^6 J
2000 * 15 * 60 J = 1.8 * 10^6 J
Use Unitary Method
Now, Rupees 4 * 0.5 = Rupees 2
1kWh = 1 BOT unit
1kWh = 1000*60*60 J = 3.6 * 10^6 J
2000 * 15 * 60 J = 1.8 * 10^6 J
Use Unitary Method
Now, Rupees 4 * 0.5 = Rupees 2

Energy = Power × Time
= 2 kW × 1/4 hour
= 0.5 kWh
= 0.5 unit
Cost = 0.5 unit × ₹4 /unit = ₹2
= 2 kW × 1/4 hour
= 0.5 kWh
= 0.5 unit
Cost = 0.5 unit × ₹4 /unit = ₹2
